com, and more particularly to means for i providing a dust and betweenthe lower edges of the sliding side doors and the bottoms of the dooropenorder that the contents of freight cars may be protected from dustand other Inatter, it is desirable that the lower edges of the doorswhen closed should not only be retained close to the adjacent edges ofthe bottoms of the door openings, but that horizontal overlapping orinterloclied strips should be interposed between the door bottoms andcar floor to prevent the ingress of dustand to form a substantiallyweatherprof joint. y

The primary object of my invention is to provide a freight car withoverlapping or interlocking strips between the lower edge of thevertical sliding doorand the bottom of the door opening, which will notinterfere with they free movement of the door into open and closedpositions, but 'which will prevent the ingress of dust to the inn teriorof the car and thereby more fully protect the contents thereof.

A further object of my invention is to prov'ide a dust and Weather-proofjoint between the lower edge of a sliding car door and the bottom of thedoor opening, which will be simple in construction, efficient in use,and convenient in application to ears of usual construction.

My invention will be more fully described. hereinafter with reference tothe accompartying drawings, in which the same is illustrated as embodiedin several convenient and practical forms, and in which- Figure 1 is anelevational view ot/a portion of the side of a freight car showing;rtht` sliding door provided with one form of my invention; Fig- 2, adetail sectional view on line 2&2, Fig. 1; and Figs. 3, 4l and 5. viewssimilar to Fig. 2, showing modified embodiments of my invention.

Similar roteren@ s are used .to

weatherproof joint designate similar parts in the several iigures oi thedrawings.

Reference letter A indicates the side of a freight car ot' any usualordinary construction. n

ll designates the oar roof and C one of the side sills which ispreferably in theform of a channel beam having its flanges projectinginwardly. as indicated in Figs. Q to 5 of the drawings.

l) indicates a sliding side door which is provided with hangers D andI)2 adjacent its top for supporting the door through engagement with atrack E of any suitable construction.

F designates the usual door guide brackcts secured to the sido sill Cand engaging the lower edge of the dool| to retain it close to the carside.

G designates the car floor which is supported upon the longitudinalsills and plo.4

jects beyond the side sills C, as shown in Figs. 2 to 5 of the drawings.

The above features of freight car construction do not in themselvesconstitute my invention, but are illustrated in order that theconstruction and operation of my invent-ion may be fully disclosed.

Referring more particularly to Figf, H designates a threshold plateoverlyin the portion of the door at the bottomo' the doos opening andprovided with a depending flange lwhich projects below the car floor.The threshold plate may be conveniently secured in position by means ofbolts. such as c, which extend through the horizontal portion thereofand also through the` door and upper flange of the channel side sill C.The depending' portion Il" of the threshold plate may also be providedwith screws, such as extending into the floor. K designates a Z-beamscoured along the bottom of the door D with one of its flanges dependingsubstantially flush with the inner surface of the door. L designates aplate secured to the inner surface 'of `the door adjacent its lower edge'and extending downwardly below the plane of the depending angc of thethreshold plate, where it is provided with an inwardly and upwardlyprojecting flange Z extending to the roar of the depending flange H ofthe threshold plate. The plate L may be 'conveniently secured to thedoor by 'means of bolts 1:" oxa tending through the same and alsothrough the door and upper flange of the vZ-loar-l K. Rivetsm are alsorovided for securing the lower flange of t e Z-bar to the adjacentportion of the plate'L. It will be observed that in this form of'myinvention the lower edge of the door is substantially flush with abovethe lower depending flange of the Z-bar K. In this form of my inventionthe door plate L is secured to the door ll by means of bolts Zzextending through the same and through the door and also through theupper flange of the Zbar K.

' n'eath the car floor by means of the bolts' -The form of my inventionshown in Fig. 4 is similar to that shown in Fig. 3, except that thethreshold plate H2 is not provided with a depending flange to interlockwith the flange on the door plate, but a separate plate N is securedbeneath the carfloor 'and is provided with a depending flange N whichextends Within the channel shaped door plate L. The plate N is securedbec extending through the same and also through the upper flange of theside sill C and car floor, and the threshold plate H2.

The form of my invention shown in Fig. 5 is similar to that shown inFig. 4, except that the door plate I2 is provided with an inwardlyvprojecting horizontal flange Z2 which serves as a weather strip andunderv lies the portion of the car floor which projects beyond the sidesill C. v

From the lforegoing description of the several forms of my inventionwhich I have herein illustrated and described, it will be observedthatfmy invention enables a dust and weather-proof joint to be formedbev tween the lower edge of a vertical sliding door and the adjacentportion of the -car floor which forms the bottom of the door opening,without in any wise interfering with the freedom of the movement of thedoor into open or closed position, but on the other hand serving tosupplement the door uide brackets in guiding the door during itsmovement, and should the door guide brackets be accidentally torn fromthe car` the interlocking flanges will serve to retain the bottom of thedoor in position against the car side and prevent it from swingingoutwardly during'the movement of the car. It will be further observedthat my invention may l^ readily applied to freight cars of usualconstruction, and serves to efficiently protecttheir-.contents rin-,l

a vertically sliding door controlling a door opening in the car side, aZ-bar secured 'along the bottom of the door with onevertical flangeoverlying the outer surface of the door adjacent the bottom thereof andthe other vertical flange depending substantially flush with the innersurface of the door, an angular weather strip having a flange overlyingrthe inner surface of the door adjacent t e bottom thereof and having aflange projecting inwardly and upwardly beneath the door opening, boltspassing through the bottom of the door and through the upwardlyextending vertical flange of said Z-bar and through the Hang@ of saidweather strip which engages the inner surface of the door, a platesecured to the car floor adjacent the bottom of the door opening andhaving a depending flange lying between said weather' strip and theupwardly projecting flange thereon, and door guide brackets securedbeneath the door opening and engaging the depending flange of said Z-barto guide the door and to prevent outward movement of the bottom thereofsufficient to injure the en gaged flanges of said weather strip andplate. i

2. In a freight car, the combination with a vertically arranged sidesill, of a floor supported upon and projecting outwardly beyond the saidside sill, a vertical sliding door controlling an opening above the earfloor, va Zihar secured .along the bottom of said door and having aflange depending in a plane substantially flush with the inner surfaceof the door,` door guide brackets secured to said side sill andextending upwardly on the outside of the depending flange of said Z-bar,a weathei'r strip secured to the depending flange of said Zbar andhaving an inwardly and upwardly projecting flange extending beneath theportion of the car floor which projects beyond said side sill, and athreshold plate having a depending flange extending between said weatherstrip and the upwardly projecting flange thereon, said depending flangeof the threshold plate and the upwardly projecting flange of saidweather strip being protected from injurious Contact by the engagementof said brackets with the depending flange of said Zsbar.
